Shawn,
I would go to the extreme of throwing the plant away because the infestation looks bad. Ants will be happliy be spreading the scale insects from one plant to another. Soon you'll find that the others are also infested.
Sundews don't usually react favourable to any form of pesticide so you may still lose it with the application.
Either way, take lots of root cuttings and soon you have enough babies to tide you over the loss of this large plant.
Do give it more light...it looks too green and floppy.
